Abstract: FIELD: medicine.  
     SUBSTANCE: invention relates to medicine, namely to experimental medicine, and can be used to develop a biological model of immunosuppression in mice. The method according to the invention includes recalculation of the maximum daily dose of dexamethasone used for a person with an average body weight of 70 kg, which is 0.143 mg / kg / day, per mouse, taking into account the dose conversion factor (DCF). DCF is the ratio of R animal  to R human , where R is the ratio of body surface to body weight, respectively, of an animal and a person, characterizes the difference in the metabolic rate of the administered drug between a mouse and a person and is equal to 11.87. The human dose of dexamethasone 0.143 mg / kg / day is multiplied by this DCF (11.87); the dose of the drug is calculated in mg of the drug per animal per day, taking into account the body weight of a particular animal. The calculated dose of dexamethasone for the animal increases by another 20%, which creates a reliable state of immunosuppression in the body of the biological model, which is confirmed in an experiment on nonlinear white mice, which were injected intraperitoneally with dexamethasone three times daily at a reasonable dose of 0.04 mg per animal per day. 
     EFFECT: use of the invention makes it possible to develop a method for calculating the dose of dexamethasone to create a biological model of immunosuppression in mice, which provides a reliable decrease in the parameters of cellular immunity, which is a prerequisite for the development of a model of immunosuppression.

Abstract: FIELD: construction. 
     SUBSTANCE: invention relates to the field of construction, it can be used in the construction of pile foundations on macro-porous soils. The method for a pile construction in macro-porous soils includes immersion of the shell with a tip in the soil, strengthening the near-pile soil by introducing a strengthening solution into it and formation of the pile trunk. The pile is formed from the shell and the composite trunk in it, and the near-pile soil is strengthened during the formation of the composite trunk. A hollow reinforced concrete pile with a pointed tip and holes in the tip and in the walls along the length of the hollow reinforced concrete pile, which is the shell of the constructed pile, is immersed in the soil to the design mark. A step-by-step strengthening of the near-pile soil and the formation of a composite pile trunk are carried out. The near-pile soil is strengthened under the pivot and around the shell of the constructed pile along its length. A part of the strengthening solution is introduced into the cavity of the reinforced concrete pile, which is forced into the ground through holes in the tip and in the walls by a hydraulic shock of piston or by means of a cylindrical trunk inserted into the cavity. After the removal of a cylindrical trunk, the lower fiber-concrete block is lowered into the cavity of the reinforced concrete pile by free fall. Part of the space above the lower block is filled with a strengthening solution. The processes of displacing the strengthening solution into the soil and lowering the next fiber-concrete block are performed. These cycles are repeated until the trunk is completely formed from fiber-concrete blocks covered by a hollow reinforced concrete pile located in the fixed soil. 
     EFFECT: increasing the load-bearing capacity of piles and pile foundations, reducing the complexity of its construction process, expanding the arsenal of technical means used in the construction of piles in macro-porous soils.
